MFC r340135: Make ng_pptpgre(8) netgraph node be able to restore order

2018-12-04T07:48:43Z

for packets reordered in transit instead of dropping them altogether. It uses sequence numbers of PPtPGRE packets. A set of new sysctl(8) added to control this ability or disable it: net.graph.pptpgre.reorder_max (1) defines maximum length of node's private reorder queue used to keep data waiting for late packets. Zero value disables reordering. Default value 1 allows the node to restore the order for two packets swapped in transit. Greater values allow the node to deliver packets being late after more packets in sequence at cost of increased kernel memory usage. net.graph.pptpgre.reorder_timeout (1) defines time value in miliseconds used to wait for late packets. It may be useful to increase this if reordering spot is distant.

mppc - Finish pluging NETGRAPH_MPPC_COMPRESSION. There were several places where reference to compression were left unfinished. Furthermore, KASSERTs contained references to MPPC_INVALID which is not defined in the tree and therefore were sure to break with INVARIANTS: comment them out.

Fix return value from ng_uncallout(). callout_stop() recently started returning -1 when the callout is already stopped, which is not handled by the netgraph code. Properly filter the return value. Netgraph callers only want to know if the callout was cancelled and not draining or already stopped. Discussed with: julian, glebius
